Family and friends of the late Allison Feldman are enthusiastic and hopeful that police have made progress in her unsolved murder. Nearly three years after her brutal murder, police have arrested a suspect whose DNA was found at the scene of the crime.

On February 17, 2015, a police news release described how the boyfriend of the victim returned home to find his girlfriend had been brutally murdered. The police identified the victim as Allison Feldman, and they confirmed that she had been beaten to death. Despite months of heavy investigation, Feldman’s murder went unsolved for almost three years.

On Tuesday, investigators arrested Ian L. Mitcham. Authorities confirmed that the suspect has been charged with first-degree murder, and police have reason to believe that he murdered Allison Feldman back in 2015. He is additionally being charged with second-degree burglary. Investigators are still attempting to piece together a motive behind this senseless crime, and it’s still unclear whether the suspect even knew the victim before murdering her.

Police were able to identify Mitcham as a suspect based on DNA evidence. Scottsdale police noted that Mitcham’s brother, who is currently imprisoned, was a partial match for DNA found at the crime scene. Interviews and tips led investigators to the current suspect. This murder case is the first investigation to utilize familial DNA testing which is a very newly developed and controversial technique.

During Mitcham’s initial court appearance, he denied knowing or having any contact with the victim. He could not give an explanation as to why his DNA was found at the crime scene.
